Housing materials
Comparing the housing materials of the HMX FJ400 and the Outemu Dustproof Red reveals significant differences that affect their sound profiles and overall performance. The FJ400 features a POM (Polyoxymethylene) top housing, which is known for creating a sound that is deep and relatively muted. This material enhances the switch's sound profile by absorbing some of the higher frequencies, resulting in a unique auditory experience that many users find pleasing. In contrast, the Dustproof Red employs a polycarbonate top housing, which contributes to a sharper, higher-pitched, and crisper sound profile due to its stiffness. The translucency of the polycarbonate also allows for improved RGB lighting effects, making it particularly attractive to aesthetic-focused users. As a result, those who prioritize sound nuances may lean toward the FJ400 for a more subdued profile, while fans of brighter sounds and visual effects may prefer the Dustproof Red.
Turning to the bottom housing, both switches utilize nylon, a classic material revered for its sound-absorbing qualities. The nylon bottom housing in both the FJ400 and the Dustproof Red promotes a deeper and fuller sound, creating a soundscape that is more rounded and less harsh than its counterparts made from harder plastics. This shared characteristic in the bottom housings means that both switches will likely deliver a similar experience in terms of the bottom-out sound, as the nylon effectively dampens vibrations for a more pleasurable tactile feedback. Therefore, regardless of the differences in their top housings, both switches benefit from the comforting qualities of nylon at the base, contributing to an enjoyable typing experience.
Ultimately, the distinction in the top housing material plays a pivotal role in shaping the overall performance of each switch. While the nylon bottom housing ensures a consistent and rounded sound profile across both models, the divergent top materials bring a unique character to each typing experience. The FJ400’s POM top fosters a deeper, muted sound, ideal for users looking for a less invasive auditory experience. Conversely, the Outemu Dustproof Red’s polycarbonate top empowers the switch with a brighter and more resonant profile, intriguing those who seek clarity and vibrant RGB displays. In essence, users can expect both switches to excel in their filler qualities due to the common nylon bottom, but their preferences will dictate which top housing sound profile aligns best with their typing style.
Weight
When comparing the HMX FJ400 linear switch and the Outemu Dustproof Red linear switch, there are some noteworthy differences in actuation and bottom out forces. The FJ400 has an actuation force of 50 grams, while the Dustproof Red is slightly lighter at 45 grams. This means that users who prefer a lighter touch for longer typing sessions may find the Dustproof Red more suitable. However, for those who enjoy a sturdier feel when typing, the FJ400's heavier actuation force might provide that satisfying resistance. When it comes to bottom out forces, the FJ400 hits 58 grams while the Dustproof Red is a bit heavier at 60 grams. This means both switches have similar bottoming out experiences, with the Dustproof Red offering a slightly stronger push at the end of the keystroke. Overall, if you favor a lighter actuation force for comfort during extended use, the Outemu Dustproof Red would be the better option, while the HMX FJ400 caters more to those who enjoy a firmer typing experience.
Travel distance
When comparing the travel distances of the HMX FJ400 linear switch and the Outemu Dustproof Red linear switch, there is a clear distinction between the two. The FJ400 features a travel distance of 3.8 mm, while the Dustproof Red offers a slightly longer travel distance of 4 mm. This means that users who opt for the FJ400 will experience a shorter keypress, which can be appealing for those who prioritize responsiveness, particularly in gaming scenarios. Conversely, the Outemu Dustproof Red, with its longer travel distance, provides a more pronounced depth that may be preferred by users who enjoy a heavier key press and a more tactile experience. Ultimately, the choice between the two will depend on individual preferences regarding key feel and responsiveness, with the FJ400 being the more responsive option and the Dustproof Red catering to those who prefer a deeper actuation.

Typing experience
When considering the sound profile of the HMX FJ400 linear switch, it is characterized as a balanced offering within the HMX Film switch lineup, providing a subtle yet pleasant acoustic experience during use. The Outemu Dustproof Red, on the other hand, does not have a widely recognized sound profile associated with it, making it difficult to define its audio characteristics. However, it's important to remember that the overall sound of a switch can also be influenced by factors such as the keyboard build and the type of keycaps used, potentially leading to similar results when both switches are employed in various setups.
Examining the feel of these switches reveals that the FJ400 is noted for providing a smooth and consistent keypress experience, which is crucial for typists and gamers alike. In contrast, the feel of the Outemu Dustproof Red is not extensively detailed, leaving its tactile feedback and actuation characteristics somewhat ambiguous. That said, both switches being linear suggests that you can expect a generally smooth keypress with minimal resistance until the bottom out, although the nuances in the feel may vary.
In summary, while the HMX FJ400 linear switch offers a balanced sound and a smooth feel that cater well to various typing preferences, the Outemu Dustproof Red remains less defined in both sound and feel descriptors. It’s crucial to consider that specific experiences may vary based on the keyboard's construction and personalized configurations, leading to potential similarities in the overall usage outcomes when both switches are used in practice.
Conclusion
To conclude, when choosing between the HMX FJ400 linear switch and the Outemu Dustproof Red linear switch, it's essential to consider your specific preferences for sound and feel. If you're looking for a balanced auditory experience and a solid, medium feel that isn't too heavy on your fingers, the FJ400 is likely the better option for you. Its 58g bottom-out force strikes a nice equilibrium that can cater to both typing and gaming needs without being overly taxing on your fingers during extended use. On the other hand, if you prefer a slightly firmer keypress and don't mind that extra bit of resistance, the 60g bottom-out force of the Dustproof Red may suit your style better. Although the Dustproof Red lacks a distinctive sound profile and isn't encapsulated by a specific reputation, its robustness and slightly heavier actuation can provide a more deliberate feel when engaging with your keyboard in a gaming or fast-paced environment. Ultimately, your choice should align with your typing habits and the intensity of use you expect, allowing you to maximize your mechanical keyboard experience.
